Repository of problems worth solving
World Solve is a public institutional repository for identifying real unresolved problems across science, society, health, governance, economics, and local systems. Each entry is intended to be citable, inspectable, and actionable.
Publicly citable
Every problem has a stable citation code for reference and discussion.
Filtered by relevance
Search by category, geography, status, and keywords.
Builder-oriented
Use the repository to find startup ideas, policy leads, and research agendas.

Space-based solar power requires transmitting multi-gigawatt microwave or laser beams safely through Earth's atmosphere. Phased array antenna precision and efficiency losses remain significant engineering bottlenecks.

Large mega-constellations reflect sunlight and emit spurious radio frequencies, interfering with ground-based optical and radio telescopes. Low-reflectivity coatings, active satellite beam steering, and mitigation software are needed.

Ground-based laser interferometers like LIGO can only hear high-frequency stellar-mass black hole collisions. Space-based interferometers with million-kilometer laser baselines (like LISA) are required.

Beamed light sails intended for Alpha Centauri must reflect 99.999% of laser light to avoid vaporizing instantly under gigawatt power. Metamaterial reflector sails with ultra-low thermal absorption must be created.

While optical communication offers high bandwidth, cloud cover blocks laser signals from deep space probes to Earth ground stations. Dynamically routed global ground-station networks and satellite relays are needed.
